AC/DC hipot testing is the effective and direct way to test insulation strength for electric equipments. It check dangerous flaws and make sure electric equipment continuous working. It typically used to test insulation strength for all kinds of electrical equipments, components like capacitors, insulation materials.
The controller should be equipped with testing transformer to boost. There are three typies of testing transformers for optional:
Oil testing transformer is popular voltage booster. It is costive which owns the features of high insulation strength and good heat dissipation.
Dry testing transformer is adopted with new technic of winding epoxy vacuum puring and CD type Iron core. It is light weight, small size, nice appearance, stable performance, easy to carry, which is suitable for on-site.
Gas testing transformer incorporates the most advanced SF6 gas application technic, with Outstanding nonflammability; Light weight, small size, no oil pollution; Unaffected by climate, little corona, long service life;
Super-light oil testing transformer. This type transformer is the most light type, which owns the features of high insulation strength and good heat dissipation.
Features
1. Over-current and zero-start voltage protection, combined aural and visual alarm;
2. New current relay, accurate and reliable;
3. Moisture-resistant and anti-shock insulation materials for the transformer.
4. AC/DC high voltage output;
5. Manual control voltage regulating;
6. Display output voltage (HV), input/testing current and withstand time at the same time;
7. In case the set input current or load current is over-range, the protection system will generate sound alarm and turn the main power off
8. Small and light weight.
